- This paper highlighted a serious deficiency in the design of a significant population of UK transmission transformers that had reached the end of life. The work indicated the need to reset transformer thermostat settings in service saving many millions pounds in replacement costs. It also prompted a review of transformer design tools and formed the motivation for the thermal work packages in phases 3 and 4 of the Transformer Research Consortium, a £2.5M industry funded project [Contact: Gordon.Wilson@nationalgrid.com].
